ARRANGEMENT IN OR RELATING TO COPY HOLDER Filed Nov. 16, 1954 BY Q JTTOfMF/J United States Patent 2,750,925 ARRANGEMENT IN OR RELATING TO COPY HOLDER Magnus Siegfried Andersen, Kapp, Ostre Toten, Norway, assignor to Sperry Rand Corporation, a corporation of Delaware Application November 16, 1954, Serial No. 469,214 Claims priority, application Norway November 18, 1953 2 Claims. (Cl. 12029) The present invention relates to copy holders of the type in which a copy holder plate, vertically moveable in relation to a frame, by depression of a lever journaled to said frame, intermittently may be transferred upwards, and where raising of said lever causes release of the plate, so that it can slide down to its initial position. Such copy holders usually are provided with a ruler resting against the copy sheet with a certain spring pressure to mark the line to be read. Generally said ruler is secured to the stationary frame and is pressed against the copy sheet by means of some suitable spring device.

The present invention has for its object to provide an arrangement in connection to said ruler, so that it automaticaliy swings out from engagement with the copy sheet when the plate moves down to its initial position.

In the known such devices, where the ruler continuously rests against the surface of the copy sheet, the ruler has a tendency to crease the paper sheets or to stick at the lower edge of the sheets when the lever is used for release so that the plate moves down to its initial position. Manually to lift the ruler away from the copy sheet during the lowering of the copy holder plate is of course cumbersome and often may be forgotten, so that the above-mentioned drawbacks occur.

According to the invention a simple and practical device is provided, whereby the ruler automatically is swung out from engagement with the copy sheet during any downwards movement of the holder plate.

To have a better understanding of the invention this will now be given a more detailed description under reference to the embodiment shown as an example in the enclosed drawing.

Fig. 1 is a perspective view of a copy holder of the usual type but provided with a device according to the invention.

Figs. 2 and 3 are respectively side and top views of that detail of Fig. l to which the invention is concerned.

The copy holder according to the drawing comprises an appropriate frame, in the present case a rear plate 11 having side edges 12 preferably secured to a base plate 14 on which the typewriter is placed. The rear plate 11, 12 supports a vertically moveable copy holder plate 8 provided with suitable means 16 for the suspension or clamping of the copy sheet, a shorthand pad, etc.

At the right side of the frame there is a lever 1 rotatably journaled in the frame at 2 and by means of a connecting rod 15 connected with the vertically extending rod 3.

A ruler 7 is, by means of the arms 6 and the cross-bar 5, rotatably journaled in the side edges 12 of the frame. The spring 13 presses the ruler against the copy sheet.

When the lever 1 is depressed the rod 3 will move upwards and a mechanism, which in the drawing, Fig. 1, is located behind the plate 8 and thus cannot be seen, causes, in a way commonly known, the plate 8, for each depression of the lever 1 to move one step upwards. The device is supposed to be provided with a stroke restricting arrangement whereby the upward transfer of the plate 8 in each step may be adjusted and thus adapted to the line spacing. Such devices are, however, well known and therefore do not need a further description.

When the copy holder plate 8 is in its upper position 2,750,925 iatented June 19, 1956 it can by moving the rod 3 in opposite direction, i. e. lifting the lever 1, be released so that it slides down to its initial position. It is during said movement that, as above mentioned the ruler 7 of the known copy holders has a tendency to crease or damage the copy sheets or stick so that the copy holder does not function.

According to the invention the cross rod 5 of the ruler 7 is provided with a small lever arm in the form of a fork plate 4 welded to the rod 5 at 17. The fork plate 4 normally protrudes substantially horizontally so that the rod 3 passes up through the arms of the fork plate. Immediately above the fork 4 a ring 9 is secured to the rod 3 by means of a split pin 19. Said details are clearly seen from Figs. 2 and 3.

During the customary step by step displacement upwards of the copy holder plate, successive depressions of the lever 1 move the rod 3 to and from the positions denoted with 9 and 9 in Fig. 2. Said movement is, as it will be seen, not obstructed by the device according to the invention. When, however, the lever 1 is raised to release the copy holder plate 8, the rod 3 during its downward movement with the ring 9 will engage the fork plate 4 thereby swinging the arms 5 carrying the ruler 7 outwards as indicated with the arrow 10. The ruler is thus moved out from its contact with the copy sheet on the holder plate 8, which plate thus, without obstructions, rapidly can be brought down to its initial or starting position.

It will be understood that according to the invention a simple and reliable device is provided whereby the above-mentioned advantages are obtained.

I claim:

1. In a copyholder, a copyholder plate mounted for vertical movement on a frame, a lever pivoted on the frame, means connecting said lever to said copyholder plate to move it upwardly in downward movement of the free end of said lever and to release said plate for downward movement in upward movement of the free end of said lever, and a copy sheet ruler mounted on said frame and normally moved toward the front face of said copyholder plate, the combination of an arm mounted on the portion of said copy sheet ruler carried by said frame, and means mounted on said first-mentioned means for engaging said arm in upward movement of the free end of said lever and moving said ruler outwardly away from said copyholder plate and copy attached thereto.

2. In a copyholder, a copyholder plate mounted for vertical movement on a frame, a lever pivoted on the frame having one end connected with an arm mounted on said frame in aligned relation to said copyholder plate, a rod mounted on said arm for movement in the operation of said lever, said arm extending in parallel adjacent relation to said copyholder plate, means on said rod operable to move said copyholder plate upwardly in downward movement of said arm and further operable to release said copyholder plate for downward movement in upward movement of said arm, a ruler having a portion extending across the front of said copyholder plate and another portion rotatably journaled in said frame, and means for normally moving said one portion of said ruler toward said copyholder plate, the combination of an arm mounted on the portion of said ruler journaled in said frame, having the free end extending into adjacent relation to said rod, and a member secured to said rod in position to engage said arm and move said one portion of said ruler outwardly from said copyholder plate when the free end of said lever is moved upwardly to secure downward movement of said copyholder plate on said frame, said outward movement of said ruler eliminating interference with copy carried by said copyholder plate.
